According to me, no animal would be able to survive in a condition where the sunlight is blocked. As the sunlight is blocked, plants will not be able to make their food as they need sunlight for the process of photosynthesis. As the plants will not get enough nutrition due lack of food, they would eventually die. By this, the herbivorous animals which feed on plants, would not get their food . Also, the the carnivorous animals which depend on the herbivorous animals for food, would not be able to satisfy their hunger as the animals they feed on would be weak or maybe even dead.

The Columbian Exchange was the arrival European people, plants, animals, and diseases in the Americas. It happened when Columbus and subsequent explorers arrived in North and South America.
So, which of these options is the most similar? It's not A, the migration to the Americas of Europeans seeking wealth and opportunity. That came much later. B, the movement of Native Americans to Europe after Columbus's voyage is also incorrect: they had no wish to move from their native lands. C, the disastrous introduction of unknown species to European ecosystems, isn't right either. Not many new species reached Europe, and they had little effect there. The transfer of plants, animals, people, and diseases between hemispheres, D, however, is correct! (Keep in mind that the Americas were in one hemisphere, and Europe is in the other.)
Answer: D
A star passes through stages of instability and stability. When core hydrogen fusion begins in a pre main sequence star, the star enters a stage of <u>stability</u>.
When the body has sufficient mass, the collapsing gas and dust burn hotter which eventually reaches temperatures enough to fuse hydrogen into helium. Thus, the star turns on and becomes a main sequence star, powered by hydrogen fusion.
A pre main sequence star is a star in the stage when it has not yet reached the main sequence. Earlier it is a protostar that grows by acquiring mass from its surrounding dust and gas.
Hence, in the pre main sequence star stage, core hydrogen fusion begins and the star enters a stage of stability.
